农田土壤酸化已成为制约农业发展的全球性问题，在强降雨淋溶地区尤为严重。本研究利用硝酸磷肥生产过程中所产生的中间产物制造的低pH值土壤调理剂来改良酸化土壤。结果表明：该调理剂按用量1 g/kg (折合亩施150 kg)即可显著地提高土壤pH值，且其在不同pH值土壤上的施用效果有所差异；施用后短期内存在返酸现象；该调理剂与约一半用量的生石灰的调控效果相当；调理剂对土壤有效磷含量的影响因土壤性质不同而异；施用调理剂对土壤有效钾的影响不显著。

Farmland soil acidification has become a global problem which has been restricted the development of agriculture. And it is particularly serious in heavy rainfall and eluvial area. This experiment uses a kind of low pH value soil conditioner which is made by intermediate product from producing the nitrophosphate fertilizer. The results show that the soil conditioner can improve soil pH value significantly with the dosage of 1 g/kg (that is the dosage 150 kg/mu), but the effects of application were different when the soil pH value were different. The soil became sour again after applying the soil conditioner within a period. Regulatory effect of the soil conditioner was the same when we halve the amount of quick lime. The effect of soil conditioner on available phosphorus content differed with soil property. The soil conditioner did not impact on content of available potassium significantly.
